S82.122G Displaced fracture of lateral condyle of left tibia, subsequent encounter for closed fracture with delayed healing

Name of the Condition

Displaced fracture of lateral condyle of left tibia, subsequent encounter for closed fracture with delayed healing

Summary

This condition involves a displaced fracture of the lateral condyle of the left tibia, a bony prominence on the outer side of the upper tibia that contributes to knee joint stability. The fracture is closed (skin intact) and represents a subsequent encounter for treatment, with delayed healing noted. Displacement means the bone fragments are out of their normal alignment, and delayed healing indicates the fracture is not progressing as expected.

Causes

Traumatic injury to the knee, such as falls, sports-related impacts, or motor vehicle accidents, is the primary cause. Direct force to the lateral knee or twisting injuries can lead to this fracture. Delayed healing may result from inadequate immobilization, poor blood supply to the fracture site, or underlying health conditions affecting bone repair.

Risk Factors

• Participation in high-impact or contact sports.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.
• Smoking or poor nutrition, which can impair healing.

Symptoms

• Persistent pain, swelling, and tenderness localized to the lateral knee.
• Difficulty bearing weight on the affected leg.
• Possible visible deformity or misalignment.
• Bruising or discoloration around the injury site.
• Lack of expected progress in healing (e.g., no visible callus formation on imaging).

Diagnosis

Physical examination to assess pain, swelling, and joint stability. Imaging tests, such as X-rays or CT scans, to evaluate fracture type, displacement, and signs of healing (e.g., callus formation). Comparison with prior imaging may be used to assess healing progress.

Treatment Options

• Prolonged immobilization with a cast or brace to promote healing.
• Surgical intervention (e.g., bone grafting, internal fixation) if healing does not progress.
• Physical therapy to maintain joint mobility and muscle strength during recovery.
• Medications to support bone healing (e.g., calcium, vitamin D) if deficiencies are present.

Prognosis and Follow-Up

Prognosis depends on the severity of displacement, patient factors (e.g., age, overall health), and adherence to treatment. Delayed healing may extend recovery time, but most fractures eventually heal with appropriate management. Regular follow-up imaging and clinical assessments are necessary to monitor progress.

Complications

• Nonunion (failure of the fracture to heal).
• Malunion (healing in an incorrect position, affecting joint function).
• Chronic pain or stiffness in the knee.
• Post-traumatic arthritis due to joint damage.
• Infection (rare, but possible with surgical intervention).

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or activities with fall risk.
• Quit smoking, as it impairs bone healing.
• Follow prescribed weight-bearing restrictions to avoid stressing the fracture.

When to Seek Professional Help

• Increasing pain, swelling, or deformity.
• Inability to bear weight on the affected leg.
• Signs of infection (e.g., fever, redness, pus).
• Lack of improvement in symptoms after several weeks of treatment.
• New or worsening numbness, tingling, or weakness in the leg or foot.

Tips for Medical Coders

This code (S82.122G) is used for a displaced fracture of the lateral condyle of the left tibia during a subsequent encounter when the fracture is closed and healing is delayed. Documentation should specify the fracture site, laterality (left), displacement, encounter type (subsequent), and healing status (delayed). Ensure alignment with clinical notes and imaging reports to support accurate coding.
